Paddling

Paddling Index methodology v1.0 · calculated 2026-09-16

76 / 100GoodData confidence: High

Shikwamkwa Lake has a heavily wooded and largely undeveloped setting, generally sheltered geometry, limited nearby major-road exposure.

Why this score?5 components

Included in the index

Component	Rating	Points of weight	Measurement
Natural setting	Excellent	33.2 of 35	95% natural land cover within 150 m of shore (91% forest, 3% wetland; 2% developed)
Geometric wind exposure	Very Good	16.2 of 29	mean fetch 1,189 m · 0% of sampled water within 500 m of shelter · generally short fetch
Motor & speed rules	Not modelled	—	Canada publishes vessel motor and speed restrictions as federal legal schedules, not map data, so they are not part of the Ontario index. Check local signage and Transport Canada rules before going out.
Public access	Good	15.0 of 18	2 MNRF fishing access points · boat ramp
Road isolation	Very Good	11.2 of 18	limited nearby major-road exposure · 1 Ontario Road Network segment within 1.2 km (traffic estimated from road class, not measured)

Additional paddling considerations

These describe the lake but are not part of the v1 Paddling Index and do not change the number above.

Wake sensitivity: Low — wide enough that wakes disperse over most of the lake
Observed motorized activity: Unknown — No lake-level measurement of boat traffic is available. Legal permission to operate motors is not evidence of use.
Wildlife habitat potential: High — 91% forest and 3% wetland cover within 150 m of shore
Mapped wildlife habitat: Mapped — Ontario MNRF has mapped moose aquatic feeding areas within 1 km of this lake. These are habitat records from provincial surveys, not animal counts; areas with nothing mapped may still hold wildlife. · Ontario MNRF Wildlife Values Area.

Compare Ontario lakes by Paddling Index →

How this index is calculated. The Paddling Index is a relative composite derived from lake geometry and public land-cover, access and road-network data. It is not a user review, a safety rating, or a prediction of an individual outing. Differences of a few points should not be treated as meaningful — an 84 and an 82 are broadly comparable. Components and weights for Ontario lakes: natural setting 35%, geometric wind exposure 29%, public access 18%, road isolation 18%. Motor and speed restrictions are not modelled for Ontario, and road traffic is estimated from road class, not measured. Where a component has no data the remaining weights are renormalized and the confidence rating is lowered; below Medium confidence no number is shown. Ontario scores are relative to other Ontario lakes and are not directly comparable with Paddling Index scores on our sister sites, which use different data sources and include a watercraft-rules component.

Quick answers

Shikwamkwa Lake — common questions

How deep is Shikwamkwa Lake?

The deepest contour on the Ontario MNRF bathymetric survey of Shikwamkwa Lake is 53.3 m (175 ft). That is the deepest depth the historical survey map records, which may differ from the deepest point of the lake itself.

How big is Shikwamkwa Lake?

Shikwamkwa Lake covers about 525 ha (1,298 acres) in Algoma District, Ontario.

Is there public access to Shikwamkwa Lake?

The Ontario MNRF lists 2 fishing access points within 100 m of the shoreline of Shikwamkwa Lake: 2 boat launches. The list includes municipal and privately owned sites, and some may charge a fee or restrict parking, so it confirms a place anglers use rather than a public right of way.
